collected in area drain to location in yard that slopes away from the house during rain <br /> events when gravity drain line surcharges. <br /> Solution (B): Disconnect all downspouts and route them to splash blocks (see Problem <br /> Identified #3). All downspouts must be disconnected so that storm water does not spill <br /> out of driveway drain or other fixtures in the house when the backwater valve closes. <br /> Solution (C): Disconnect downspouts where yard area is available to route splash <br /> blocks to (see Problem Identified #3). Install a check valve on the floor drain so that it is <br /> protected against surcharge events <br /> 3) (OPTIONAL IMPROVEMENT) Downspouts are tied into side sewer. This causes <br /> increased flow in the side sewer. <br /> Solution A: Disconnect downspouts from side sewer, extend outfall 3' or more from <br /> foundation, and provide splash block. Cap existing downspout lines in the ground. <br /> Solution B: Disconnect downspouts and install rain barrels to retain rain water runoff at <br /> base of downspouts. Cap existing downspout lines in the ground. <br /> As-Built of Sewer and Plumbing <br /> See attached drawing. <br /> Comments <br /> • All down spouts that are connected to the side sewer could be disconnected and <br /> routed to splash blocks so that less flow is in the side sewer causing potential <br /> surcharge events. Where downspouts are routed to splash blocks the ground <br /> surface should be sloped away from the house. Southern 2 downspouts are in <br /> good location for disconnection. <br /> • Installing a grinder pump would provide increased protection from sewer backups <br /> beyond the protection a backwater valve can provide. <br /> Additional Photos and Descriptions <br /> • <br /> Backwater valve installation location <br /> 411 immediately downstream of cleanout. <br /> S:\#Common\clerical\SIDE SEWER&PLUMBING INVESTIGATION\Final Reports\Sewer L Batch\1232 Lombard Ave final.docx 4/28/2011 <br />
